Embodiment 1

[0024] Embodiment 1: with reference to attached Figure 1-5 . A mask, comprising a transparent cover body 1, two layers of outer edges 5, 6 are arranged on the edge of the transparent cover body 1, positioning grooves are formed between the two layers of outer edges 5, 6, and a silicone sleeve 3 is set in the tightening hoop of the positioning grooves, The transparent cover body 1 is provided with at least one air outlet area, and the air outlet area is covered with a filter sheet 2, and the air outlet area is provided with hollow holes and several valve holes 7 spaced apart from each other, and the filter sheet 2 has barbs 8 positioned in coordination with the valve holes 7 According to the needs of the environment, different filter sheets 2 can be replaced to achieve different defensive effects. When replacing, push the barb 8 outward from the inner surface of the transparent cover body 1, so that the barb 8 is out of position, and can be removed from the outer surface of th...

Embodiment 2

[0025] Embodiment 2: with reference to attached Figure 1-5 . A mask, the shape of the air outlet area matches the shape of the filter sheet 2, and the internal hollows also correspond to each other, and at least two valve holes 7 are arranged in the air outlet area, and the number of barbs 8 on the filter sheet 2 is consistent with the number of valve holes 7. .

Embodiment 3

[0026] Embodiment 3: with reference to attached Figure 1-5 . A mask, in which at least two barbs 8 of a filter sheet 2 are arranged in opposite directions.

Abstract

The invention relates to a respirator. The respirator can be fitted with the human face tightly, filter sheets with different effects can be replaced conveniently under different environments, and the respirator can be used for being adaptive to different environments. The respirator comprises a transparent cover body, two layers of outer edges are arranged on the edge of the transparent cover body, a locating groove is formed between the two layers of outer edges, a silicon rubber case is mounted in the locating groove in tight hooping and sleeved modes, at least one air outlet area is arranged on the transparent cover body, one filter sheet covers the air outlet area, hollowed-out holes and a plurality of valve openings are formed in the air outlet area in a mutual interval mode, and barbs matched with the valve openings for locating are arranged on the filter sheets. The respirator has the advantages that the filter sheets can be replaced according to different environments, and the purpose of different respirator effects can be achieved; the filtering effect of the filter sheets in the respirator is reduced due to long-time using, after a new filter sheet is replaced, the respirator can be used again, and the effect is improved, the filter sheet and the respirator are separated, and cleaning is easy.

Description

technical field [0001] The invention relates to a mask, in particular to a mask that can closely fit a human face and can conveniently replace filters with different effects in different environments, so as to adapt to different environments. Background technique [0002] Existing masks have only one function and cannot be used to defend against a certain pollution in a specific environment; or the existing masks have too many functions and cannot effectively defend against a single pollution in a specific environment. to the desired effect. [0003] The mask cannot be effectively used for the second time after use, and its defense effect cannot meet the requirements. [0004] When using a transparent mask, the water vapor produced by the human body will cause fog inside the mask, which will affect the conversation effect. Contents of the invention [0005] Design purpose: To avoid the deficiencies in the background technology, to design a mask that can closely fit the h...
